Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed llpril 29. 1904. Serial No. 206,485.

To all whom, it may concern:

Be it known that I, RICHARD W. J EFFERIS, of Camden, county of Camden,and State of New Jersey, have invented an Improvement in LookingDevices, of which the following is a specification.

My improved locking devices are especially adapted for use in connectionwith metal lockers for the purpose of locking the door to thelocker-frame.

My improvements relate particularly to that class of door fasteningswhich employ a pivoted latch and to the combination of such a latch witha key-actuated lock to lock the latch against movement.

My "invention also embraces means for locking the latch-leverindependently of the key-actuated lock The use of spring-locks inclothes-lockers is very objectionable, as it frequently happens that thedoor is closed while the user of the locker is without his key andsometimes when the key is, in fact, in a pocket of the clothes in thelocker. To avoid this difficulty, I employ in the present lockingdevices a latch-fastening which may be either spring-actuated orgravity-actuated and a key-actuated lock, the bolt of which moves in thepath of a projection on the latch and prevents it from being actuated toopen the door. The latch is also provided with an eye,

by which it may be positively locked independcntly of the key-actuatedlook.

In the drawings, Figure 1 is a frontelevation of the locking devices.Fig, 2 is a side elevation, and Fig. 3 is a rear elevation.

11 is a vertical jamb-post.

I) is the vertical iron of the door-frame which carries the lockingdevices.

c is a latch-lever pivoted, as at c, to the iron I) and having thethumb-piece (1 projecting through a slot (1! in the front of the ironI). Carried by the back of the lever is a hook or catch e, adapted toengage the usual lug non the jamb-post. The thumb-piece d is providedwith an eye (1 Carried by the latch-lever c is a projection or wing f,which occupies a normal position immediately adjacent to the bolt of thelock 9 so that when the atch-lever is moved the wing f must swing infront of the end of the retracted bolt. In Fig. 3 the bolt-.0 is shownprojected.

h is a slide guided in the back of the iron I) and connected by links t'i with the catches j j, guided in suitable guide-blocks 7c. Thesecatches are adapted to engage suitable lugs on the jamb-post. The slideit is connected by a suitable link m with the catch e.

In the construction shown the locking devices are actuated by gravityunder the control of the latch-lever c. It is obvious that they may bespring-controlled by a spring acting on the latch-lever in the usualmanner.

While the bolt is retracted the latch may be actuated to unfasten thedoor; but when the bolt is shot it projects in the path of the wing orprojection f and prevents the latch frombeing actuated. The latch mayalso be locked by a padlock inserted in the eye (1 What I claim as new,and desire to secure by Letters Patent, is as follows:

1. In a locking device for lockers and the like, the combination of apivoted latch lever having a projection f extending transversely to theplane of oscillation of the latch-lever, and a key-actuated bolt movabletransversely to the plane of oscillation of the latch-lever and in thepath of said projection f.

2. In a locking device for lockers and the like, the combination of apivoted latch-lever oscillating in a plane transverse to the plane ofthe door and having a projection extending transversely to the plane ofoscl lation of said latch-lever and akey-actuated bolt carried by thedoor and movable in a planeparallel to the plane of the door arid in thepath of the projection f of the latch-lever.

In testimony of which invention I hereunto set my hand.
